[0002] With the increasing popularity of plastic products, a large amount of plastic waste is generated in daily life. Now, it has entered a period of plastic waste flooding. In particular, plastic building blocks, as a creative toy, are of great significance to the growth and development of children. With the large-scale production of plastic building blocks, a large amount of waste building blocks are also generated. Therefore, how to recycle waste building blocks has become an urgent problem to be solved at present.

[0003] A patent with the publication number CN118144152B discloses a plastic waste recycling device, including a support platform, a water storage tank, a cleaning tank, a crushing tank, a crushing device, a cleaning device, a first transmission assembly, a second transmission assembly, and a driving assembly. Among them, the water storage tank is fixedly arranged on the support platform, and a water inlet pipe and a water outlet pipe are respectively arranged at both ends of the water storage tank. Through the cooperation of the first cleaning assembly and the second cleaning assembly, the stains on the plastic fragments can be effectively removed, improving the cleaning effect and efficiency, so as to ensure the quality of the plastic products after reprocessing.

[0004] The above solution still has some problems in actual application.

After that, they are put into a plastic granulator for granulation to complete the recycling work of waste building blocks. Although this recycling method can make the waste building blocks fully contact with the cleaning liquid, however, it can only clean the waste building blocks batch by batch, and after cleaning a batch of waste building blocks, the cleaning pool needs to be cleaned and new cleaning liquid needs to be replaced, which is not only cumbersome to operate but also has low cleaning efficiency.

[0021] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0022] Example 1, as Figures 1 to 9 shown, an automatic recycling device for plastic toy waste described in an embodiment of the present invention includes a cleaning pool 1 and a drying box 2 installed on one side of the cleaning pool 1. A heating cover plate 3 is installed at the upper end of the drying box 2, and a distribution box 4 is installed at the upper end of the heating cover plate 3. Two cleaning conveying assemblies 6 are rotatably arranged in the inner cavity of the cleaning pool 1; The cleaning conveying assembly 6 includes two cross rotating frames 61 rotatably arranged in the inner cavity of the cleaning pool 1, and the two cross rotating frames 61 are arranged at an angular dislocation for circularly collecting waste building blocks into the bottom of the cleaning pool 1 for cleaning; T-shaped sliding rods 62 are slidably connected inside the cross rotating frames 61. One end of each T-shaped sliding rod 62 is fixedly connected with an installation block 65. A fixed plate 8 is rotatably connected between the installation blocks 65. A scoop net 7 is fixedly connected between the fixed plates 8. The scoop net 7 is made of a stainless steel mesh plate and is arranged in a semi-circular shape for scooping out the waste building blocks in the cleaning pool 1 for conveying; Two brush rollers 25 are installed at the upper end of the cleaning pool 1, and the brush rollers 25 slide inside the scoop net 7 for brushing and cleaning the garbage and stains inside the scoop net 7.

[0023] Specifically, in the prior art, waste building blocks are usually put into a cleaning pool filled with cleaning liquid, and then the waste building blocks are stirred and cleaned by a motor-driven stirring rod. Although this cleaning and recycling method can make the waste building blocks fully contact with the cleaning liquid, it can only clean the waste building blocks batch by batch. Moreover, after cleaning a batch of waste building blocks, the cleaning pool needs to be cleaned and new cleaning liquid needs to be replaced, which is not only cumbersome in operation but also low in cleaning efficiency; When the present invention recycles waste building blocks, by driving the cross rotating frame 61 to rotate, and making the cross rotating frame 61 drive the T-shaped sliding rod 62 to rotate, at the same time the T-shaped sliding rod 62 drives the mounting block 65 to rotate, and then drives the fixing plate 8 to rotate. During the rotation of the fixing plate 8, the scoop net 7 will be driven to rotate synchronously. Then, after the scoop net 7 slides into the inner cavity of the cleaning pool 1, it will scoop and clean the waste building blocks in the inner cavity of the cleaning pool 1. Then, as the cross rotating frame 61 continues to rotate, the waste building blocks in the inner cavity of the cleaning pool 1 will be scooped out, and at the same time, the scooped waste building blocks will be poured into the drying box 2 for drying treatment. After pouring out the waste building blocks inside, the cross rotating frame 61 drives the scoop net 7 to rotate upward, so that the scoop net 7 slides outside the brush roller 25. After the scoop net 7 slides outside the brush roller 25, the scoop net 7 rotates with the cross rotating frame 61, making the scoop net 7 rotate outside the brush roller 25. Then, the brush on the outside of the brush roller 25 is used to brush and clean the inner cavity of the scoop net 7, and at the same time clean the mesh holes of the scoop net 7, avoiding the blockage of the mesh holes of the scoop net 7 by sludge and other garbage generated during the cleaning of waste building blocks, resulting in the situation that the scoop net 7 cannot drain the water from the cleaned waste building blocks after scooping them out. At the same time, by using the brush roller 25, the inner cavity of the scoop net 7 can also be brushed and cleaned, avoiding the residue of sludge and other garbage generated during the cleaning of waste building blocks in the scoop net 7, resulting in the pollution of the cleaned waste building blocks by the sludge and other garbage remaining in the inner cavity of the scoop net 7 when the scoop net 7 scoops out and recycles the waste building blocks for subsequent cleaning, affecting the cleaning effect of waste building blocks, thus solving the above problems.

[0024] As Figure 1 、 Figure 2 and Figure 7 shown, a guide plate 5 is fixedly connected to one side of the cleaning pool 1 for guiding waste building blocks into the cleaning pool 1. A semi-circular mesh plate 11 is installed at the bottom of the inner cavity of the cleaning pool 1. A brush is arranged outside the brush roller 25, and the brush is made of PET polyester material, having good wear resistance and hardness, and can brush and clean the garbage and stains in the inner cavity and mesh holes of the scoop net 7.

[0025] Specifically, when cleaning and recycling waste building blocks, the piled-up waste building blocks are put into the guide plate 5 by means of a conveyor belt, and the guide plate 5 is used to guide the waste building blocks into the semi-circular mesh plate 11, and then the cleaning and conveying assembly 6 is used to circulate and clean and convey the waste building blocks.

[0026] As Figure 1 、 Figure 4 and Figure 7 shown, a plurality of storage grooves 66 are formed inside the cross rotating frame 61, and a spring 67 is fixedly connected to the bottom of each storage groove 66. One end of the spring 67 is fixedly connected to the T-shaped sliding rod 62. A support column 63 is fixedly connected inside the cross rotating frame 61, and the support column 63 is rotatably installed inside the upper end of the cleaning pool 1. Brushes are uniformly arranged outside the scoop net 7 for brushing and cleaning the semi-circular mesh plate 11.​​

[0027] Specifically, by driving the cross-shaped rotating frame 61 to rotate, and causing the cross-shaped rotating frame 61 to drive the T-shaped sliding rod 62 to rotate. At the same time, the T-shaped sliding rod 62 drives the mounting block 65 to rotate, and then drives the fixing plate 8 to rotate. During the rotation of the fixing plate 8, the scoop net 7 will be driven to rotate synchronously. After the scoop net 7 slides into the inner cavity of the cleaning pool 1, the scoop net 7 will drive the fixing plate 8 to push the mounting block 65 to contract. At the same time, the mounting block 65 drives the T-shaped sliding rod 62 to slide into the inner cavity of the storage groove 66 for contraction. After the scoop net 7 slides into the inner cavity of the cleaning pool 1, by using the spring 67 to bounce up the T-shaped sliding rod 62, and making the T-shaped sliding rod 62 push the mounting block 65 to drive the fixing plate 8 and the scoop net 7 to closely fit with the inner cavity of the semi-circular net plate 11. Thus, it is convenient for the scoop net 7 to scoop out and collect the waste building blocks in the cleaning pool 1. Moreover, during the process of scooping out the waste building blocks in the inner cavity of the cleaning pool 1, since the outer part of the scoop net 7 is evenly provided with brushes, the brushes can be used to brush and clean the semi-circular net plate 11 at the bottom of the inner cavity of the cleaning pool 1, preventing the sludge and garbage generated from the cleaning of the waste building blocks from blocking in the semi-circular net plate 11 and affecting the subsequent cleaning of the waste building blocks. This solves the problem that in the existing automatic recycling equipment for plastic toy waste, when recycling waste building blocks, it is inconvenient to automatically clean the waste building blocks, scoop them out and collect them from the cleaning pool, and it is also inconvenient to brush the filter net plate in the cleaning pool when scooping out the waste building blocks. The sludge and garbage generated from the cleaning of the waste building blocks block the mesh holes of the filter net plate, resulting in the water in the cleaning pool becoming dirtier and dirtier with use. After a long time of use, it is necessary to drain the water in the cleaning pool and clean the filter net plate separately, which not only affects the recycling efficiency of the waste building blocks but also cannot achieve automatic recycling.

[0028] As Figure 4 、 Figure 7 and Figure 9 shown, a disc 26 is fixedly connected to the outside of the inner cavity of the mounting block 65 on the fixing plate 8. A torsion spring 27 is fixedly connected to one side of the disc 26. One end of the torsion spring 27 is fixedly connected to the inner cavity wall of the mounting block 65. One end of the fixing plate 8 penetrates through the mounting block 65 and is fixedly connected to a gear 64.

[0029] Specifically, after the cross rotating frame 61 drives the scoop net 7 to slide out of the inner cavity of the cleaning pool 1, the driving gear 64 is rotated, and the gear 64 drives the fixing plate 8 to rotate. Then, the fixing plate 8 drives the disc 26 to rotate the torsion spring 27, and at the same time, the fixing plate 8 drives the scoop net 7 to rotate. Furthermore, the scoop net 7 dumps the cleaned waste building blocks scooped out from the inner cavity into the second cleaning pool for secondary cleaning. Then, the cleaned waste building blocks are dumped into the drying box 2 by the cleaning and conveying component 6 for drying treatment. After the scoop net 7 dumps the cleaned waste building blocks into the drying box 2, the torsion spring 27 drives the disc 26 to rotate and reset. Then, the disc 26 drives the fixing plate 8 to rotate and at the same time drives the scoop net 7 to rotate and reset, thus realizing the cyclic cleaning and recycling of the waste building blocks in the inner cavity of the cleaning pool 1, and solving the problem that the existing automatic recycling equipment for plastic toy waste is inconvenient for cyclic cleaning and recycling of waste building blocks when recycling them. As a result, when recycling waste building blocks, since only the cleaning pool can be used to clean the waste building blocks batch by batch, then pour them into the drying box for drying treatment, and then use a plastic granulator to process and granulate to complete the recycling of waste building blocks, which not only has cumbersome operation but also affects the recycling efficiency of waste building blocks.

[0030] As Figures 1 to 4 and Figure 7 shown, a plurality of mounting plates 22 are installed at the upper end of the cleaning pool 1, and a rack 23 is fixedly connected to one end of the inner cavity of the cleaning pool 1 among the plurality of mounting plates 22. The rack 23 is meshed with the gear 64, and a fixing frame 24 is fixedly connected to the upper end surface of the mounting plate 22. The brush roller 25 is rotatably connected to the fixing frame 24.

[0031] Specifically, when driving the cleaning and conveying assembly 6 to operate, the cross-rotating frame 61 drives the T-shaped sliding rod 62 to rotate, and at the same time drives the mounting block 65 to rotate, and then the mounting block 65 drives the fixing plate 8 and the scoop net 7 to rotate synchronously. After the scoop net 7 rotates and slides out of the inner cavity of the cleaning pool 1, the fixing plate 8 will drive the gear 64 to mesh with the rack 23, so that the gear 64 rotates, and at the same time drives the fixing plate 8 to rotate, and then drives the scoop net 7 to rotate, so that the scoop net 7 dumps the waste building blocks in the inner cavity into the drying box 2 for drying treatment. After dumping the waste building blocks inside, the cross-rotating frame 61 drives the scoop net 7 to rotate upward, so that the scoop net 7 slides outside the brush roller 25. After the scoop net 7 slides outside the brush roller 25, the scoop net 7 rotates with the cross-rotating frame 61, so that the scoop net 7 rotates outside the brush roller 25, and then uses the brush on the outside of the brush roller 25 to brush and clean the inner cavity of the scoop net 7, and at the same time clean the mesh holes of the scoop net 7, avoiding the blockage of the mesh holes of the scoop net 7 by sludge and other garbage generated by the cleaning of the waste building blocks, resulting in the situation that the scoop net 7 cannot drain the water of the cleaned waste building blocks after scooping them out. At the same time, by using the brush roller 25, the inner cavity of the scoop net 7 can be brushed and cleaned, avoiding the residue of sludge and other garbage generated by the cleaning of the waste building blocks in the scoop net 7, resulting in the pollution of the cleaned waste building blocks by the sludge and other garbage remaining in the inner cavity of the scoop net 7 when the scoop net 7 scoops out and recycles the waste building blocks for subsequent cleaning, affecting the cleaning effect of the waste building blocks.

[0032] Embodiment 2, as Figures 2 to 7 shown, a servo motor 9 is installed at one end of the cleaning pool 1, and the output shaft end of the servo motor 9 is fixedly connected to the support column 63 located on one side of the cleaning pool 1. A driving mechanism 10 is provided at one end of the support column 63, and the driving mechanism 10 is used to drive the two cleaning and conveying assemblies 6 to operate.

[0033] As Figures 1 to 4 and Figure 8 shown, the driving mechanism 10 includes an L-shaped fixing block 103 installed at one end of the cleaning pool 1. A rotating shaft 102 is rotatably connected inside the L-shaped fixing block 103. Driven bevel gears 104 are fixedly connected to both ends of the rotating shaft 102. The driven bevel gears 104 are meshed with a driving bevel gear 101, and the driving bevel gear 101 is fixedly connected to the support column 63.

[0034] Specifically, when cleaning and recycling waste building blocks, the servo motor 9 is started to drive the support column 63 to rotate, and the support column 63 drives the transmission bevel gear 101 to rotate. At the same time, the transmission bevel gear 101 meshes with and drives the driven bevel gear 104 to rotate, and then drives the rotating shaft 102 to rotate. During the rotation of the rotating shaft 102, it will drive the driven bevel gear 104 to rotate. At the same time, the driven bevel gear 104 meshes with and drives the transmission bevel gear 101 to rotate, and then drives the support column 63 to rotate. During the rotation of the support column 63, it will drive the cross rotating frame 61 to rotate, and the cross rotating frame 61 drives the T-shaped slide bar 62 to rotate. At the same time, the T-shaped slide bar 62 drives the mounting block 65 to rotate, and further drives the fixing plate 8 and the scoop net 7 to rotate synchronously. During the rotation of the scoop net 7, it will cycle to scoop out the waste building blocks in the inner cavity of the cleaning tank 1 for conveying, so as to realize the automatic cleaning and recycling treatment of waste building blocks, and thus solve the problem that when the existing automatic recycling equipment for plastic toy waste recycles waste building blocks, due to the inconvenience of automatically cleaning the waste building blocks and scooping them out of the cleaning tank for recycling, the recycling efficiency of waste building blocks cannot achieve automatic recycling.

[0035] As Figures 1 to 4 and Figure 8 shown, a transmission belt pulley 20 is fixedly connected to the outside of the support column 63 on one side of the cleaning tank 1. The outside of the transmission belt pulley 20 is drivingly connected with a belt 19. One end of the belt 19 is drivingly connected with a driven belt pulley 21. A rotating column 15 is fixedly connected to the inside of the driven belt pulley 21. A plurality of fixing rods 16 are fixedly connected to the outside of the rotating column 15, and one end of the plurality of fixing rods 16 is fixedly connected with an inclined conveying plate 17, which is used for stirring the cleaned waste building blocks and conveying the waste building blocks to the external plastic granulator for recycling treatment during the stirring process.

[0036] As Figure 1 、 Figure 7 and Figure 8 shown, a semi-circular filter screen 14 is installed in the inner cavity of the drying box 2. The semi-circular filter screen 14 is used for filtering the water in the cleaned waste building blocks. An outlet 18 is opened at one end of the drying box 2, and the outlet 18 is communicated with the inner cavity of the semi-circular filter screen 14.

[0037] Specifically, when the driving cleaning and conveying assembly 6 automatically cleans and recycles waste building blocks, the support column 63 drives the cross-shaped rotating frame 61 to rotate. At the same time, the cross-shaped rotating frame 61 drives the T-shaped slide rod 62 and the mounting block 65 to rotate, and the mounting block 65 drives the fixing plate 8 and the scoop net 7 to rotate. As a result, the scoop net 7 scoops out the cleaned waste building blocks, controls the water, and dumps them into the drying box 2. During the rotation of the support column 63, the driving pulley 20 is driven to rotate. At the same time, the driving pulley 20 drives the transmission belt 19 to rotate, and then drives the driven pulley 21 to rotate. At the same time, the driven pulley 21 drives the rotating column 15 to rotate, and the rotating column 15 drives the fixing rod 16 to rotate, and then drives the inclined conveying plate 17 to rotate. During the rotation of the inclined conveying plate 17, the waste building blocks put into the semi-circular filter net 14 are turned over, so that the water in the cleaned waste building blocks is filtered out through the semi-circular filter net 14. And then, in cooperation with the heating cover plate 3 to heat the inner cavity of the drying box 2, the waste building blocks in the semi-circular filter net 14 are quickly dried. Moreover, during the rotation of the inclined conveying plate 17, the waste building blocks are circularly conveyed and moved towards the discharge port 18, and then the dried waste building blocks are discharged into the plastic granulator through the discharge port 18 for recycling and granulation, thus realizing the automatic recycling process of waste building blocks, and solving the problem that the existing automatic recycling equipment for plastic toy waste, due to the traditional plastic recycling process of pouring waste building blocks into a bucket filled with cleaning liquid in batches and driving the stirring rod by a motor to stir and clean the waste building blocks. Although this method can make the waste building blocks fully contact with the cleaning liquid, it cannot realize the cyclic automatic cleaning and recycling of waste building blocks, and automatically put the cleaned waste building blocks into the drying equipment for drying, and at the same time automatically convey them into the plastic granulator for granulation, resulting in low recycling efficiency of waste building blocks and inability to realize automatic recycling and treatment.

[0038] As Figure 1 , Figure 7 and Figure 8 shown, a partition plate 12 is fixedly connected to the bottom of the inner cavity of the cleaning pool 1, and the semi-circular net plate 11 is installed at the upper end of the partition plate 12. The partition plate 12 divides the cleaning pool 1 into two cleaning chambers for two-cycle cleaning of waste building blocks.

[0039] Specifically, when cleaning and recycling waste building blocks, the semi-circular net plate 11 is used to filter the clear water in the inner cavity of the cleaning pool 1. And the partition plate 12 divides the cleaning pool 1 into two cavities, and then the waste building blocks are subjected to two cleaning and recycling processes through the two cavities, improving the cleaning effect of the waste building blocks. Moreover, the setting of the semi-circular net plate 11 can filter the sludge in the clear water into the bottom of the inner cavity of the cleaning pool 1, preventing the sludge from accumulating in the inner cavity of the semi-circular net plate 11. When the scoop net 7 rotates into the inner cavity of the semi-circular net plate 11, the sludge in the inner cavity of the semi-circular net plate 11 will be scooped up, causing the clear water to become turbid again and affecting the cleaning effect of the waste building blocks.

[0040] Working principle: By driving the cross rotating frame 61 to rotate, and making the cross rotating frame 61 drive the T-shaped slide bar 62 to rotate. At the same time, the T-shaped slide bar 62 drives the mounting block 65 to rotate, and then drives the fixing plate 8 to rotate. During the rotation of the fixing plate 8, the scoop net 7 will be driven to rotate synchronously. After the scoop net 7 slides into the inner cavity of the cleaning pool 1, the scoop net 7 will drive the fixing plate 8 to push the mounting block 65 to contract. At the same time, the mounting block 65 drives the T-shaped slide bar 62 to slide into the inner cavity of the storage groove 66 for contraction. After the scoop net 7 slides into the inner cavity of the cleaning pool 1, by using the spring 67 to pop up the T-shaped slide bar 62, and making the T-shaped slide bar 62 push the mounting block 65 to drive the fixing plate 8 and the scoop net 7 to closely fit the inner cavity of the semi-circular net plate 11, so as to facilitate the scoop net 7 to scoop out and collect the waste building blocks in the cleaning pool 1. Moreover, during the process of scooping out the waste building blocks in the inner cavity of the cleaning pool 1, since the outer part of the scoop net 7 is evenly provided with brushes, the brushes can be used to brush and clean the semi-circular net plate 11 at the bottom of the inner cavity of the cleaning pool 1, avoiding the sludge and garbage generated by the cleaning of the waste building blocks from being blocked in the semi-circular net plate 11 and affecting the subsequent cleaning of the waste building blocks; When driving the cleaning and conveying assembly 6 to automatically clean and recycle the waste building blocks, the support column 63 will drive the cross rotating frame 61 to rotate. At the same time, the cross rotating frame 61 drives the T-shaped slide bar 62 and the mounting block 65 to rotate, and makes the mounting block 65 drive the fixing plate 8 and the scoop net 7 to rotate, so that the scoop net 7 scoops out the cleaned waste building blocks, controls the water, and dumps them into the drying box 2. During the rotation of the support column 63, it will drive the transmission pulley 20 to rotate. At the same time, the transmission pulley 20 drives the transmission belt 19 to rotate, and then drives the driven pulley 21 to rotate. At the same time, the driven pulley 21 drives the rotating column 15 to rotate, and makes the rotating column 15 drive the fixed rod 16 to rotate, and then drives the inclined conveying plate 17 to rotate. During the rotation of the inclined conveying plate 17, it will turn over the waste building blocks put into the semi-circular filter net 14, so that the water in the cleaned waste building blocks is filtered and discharged through the semi-circular filter net 14. And then, in cooperation with the heating cover plate 3 to heat the inner cavity of the drying box 2, the waste building blocks in the semi-circular filter net 14 can be quickly dried. Moreover, by using the inclined conveying plate 17 during the rotation process, the waste building blocks are circulated and conveyed to move towards the discharge port 18, and then the dried waste building blocks are discharged into the plastic granulator through the discharge port 18 for recycling and granulation, so as to realize the automatic recycling process of the waste building blocks.
